BED-SPRING.

SPECIFICATION forming part of Letters Patent No. 681,748, datedSeptember 3, 1901. Application filed October 24, 1900. fierial No.34,193. (No model.)

To CI/ZZ whom it may concern:

Be it known that I, CHARLES G. SMITH, a citizen of the United States,residing at Lakeland, in the county of Livingston and State of Michigan,have invented a new and useful Bed-Spring, of which the following is aspecification.

This invention relates to bed-springs, and particularly to means forconnecting spring or yielding sections or portions thereof; and theobject of the same is to provide a simple and effective deviceforadjustablyattaching the sections or portions in a strong and durablemanner, whereby the tension of the springs as an entirety can beregulated to suit the requirements of different users and also providefor the replacement of any part by another in the event of injury orbreakage.

The invention consists of the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the drawings, Figure 1 is a perspective view of aseries of bed-springsections shown attached by the improved connector. Fig. 2

' is a plan view of a portion of two sections,

showing the one terminal of the connector attached to the end of onesection and the opposite terminal in position for securement to the endof the other section. Fig. 3 is aview similar to Fig. 2, showing theattachment of the connector completed and showing one end of the latterbent over a greater distance than the connectors shown by Fig. 1. Fig. 4is a longitudinal vertical section of two of the sections and aconnector, showing the manner of increasing the tension of the twosections.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The spring fabric is composed of a series of wire sections comprising asingle wire bent zigzag, forming loops 1, having one end closed and theopposite end open, said loops being alternately arranged, so that theopen ends of one set of loops come between the closed ends of the otherset of loops. The side members 2 are crimped or waved, therebypermitting the loops to have a linear spring action, so as to expand andcontract. The crimps or waves are in the plane of the fabric orbed-bottom to provide an extended. surface for the mattress or othercovering and also to prevent the strain coming upon the crests or apicesof the crimps and destroying their elasticity, all of which is clearlydisclosed in Patent No. 609,842, granted to me August 30, 1898. In thepresent construction the engaging hooks of the device shown by saidpatent are dispensed with, and the latter hooks are replaced byconnectors 3, formed of elongated flat or suitable sheetmetal stripshaving sufficient strength to resist the strain brought to bear thereon,and each provided with a series of openings 4, ex-

tending longitudinally thereof for the insertion of a suitable implementto turn over one end in primarily completing the application of theimproved device and in changing the adjustment of the same.

The portions of the loops 1 which are connected and contiguouslyarranged have straight transverse end bars 5, and in applying eachconnector thereto the one end of the latter is first bent into a hook 6of compara-' tively limited extent and caught over one bar 5, and theopposite extremity of the connector will then be disposed under theopposite bar 5, as clearly shown by Fig. 2. By inserting any suitableimplement having a slightlyhooked end through one of the openings 4, inaccordance with the tension desired and from the bottom and bracing itagainst the bar to which the final attachment is to be made theunattached end of the connector is bent over the bar and the desired orrequisite tension on the loop so connected simultaneously acquired. Inchanging the adjustment, as indicated by dotted lines in Fig. 4, thefinally-attached extremity of the connector, as just set forth, isopened or bent back and subsequently rebent at a different point by thesame means to produce a longer or shorter hook, as the case may be, andthereby users of the improved bed-spring can regulate the tension of thesame to suit their individual tastes.

Theimproved device is simple and inexpensive in its nature and is easilyand readily applied. Moreover, the application and adj ustment can bemade without requiring the assistance of a skilled mechanic to obtainthe result sought, and though the simplest and preferred form of theimproved device has been shown and described? it is obviously apparentthat changes in the shape or general contour, as well as the size andproportions, can be resorted to Without departing from the spirit of theinvention.

Having thus described the invention, What is claimed as new is- Thecombination with a bed-bottom comprising a series of loops havingparallel sides and closed ends in planes at right angles to the sidesand spaced apart in longitudinal alinement, of elongated flat metalconnectors having the full transverse extent of the ter-
